Wag/a2 M v ATTORNEY-5 3,548,668 DUAL ECCENTRIC SHAKER Joseph A. Amori, 1270 Pine Ave., San Jose, Calif. 95125 Filed May 29, 1969, Ser. N 0. 828,999 Int. Cl. B07b 1/30; F1611 25/18 US. Cl. 74-61 2 Claims ABSTRACT OF THE DISCLOSURE The objects. and advantages of the invention will be apparent from the following description taken in conjunction with drawings forming part of the specification, and in which:

FIG. 1 is a partly sectionalized view in side elevation;

FIG. 2 is a partly sectionalized top plan view of the apparatus of FIG. 1;

FIG. 3 is an enlarged detailed view taken along lines 3-3 of FIG. 2;

FIG. 4 is an enlarged detailed view taken along lines 4-4 of FIG. 2;

FIG. 5 is an enlarged detailed view taken along lines 5-5 of FIG. 2; and

FIG. 6 is an enlarged detailed view taken along lines 6-6 of F IG. 2.

With reference to FIG. 1, a framework 10 comprised of upright members 12, horizontal members 14, inclined strut members 16, and arcuate members 18 is illustrated. The frame 10 is for an apricot halving and pitting machine of the type shown in US. Letters Pat. 2,827,089, pocket-defining roller members moving upwardly over the upper members 18 in fruit-bearing condition and moving downwardly over the lower members 18 in empty condition. Such a machine is just one of the many environments of use for the subject invention, the pan or bed of which is disposed underneath the upper run of the fruit conveyor to catch fruit, twigs, etc., which fall through the upper reach of the fruit conveyor and to convey the same to a cross-conveyor for movement out of the zone of the fruit-handling machine.

For the support of this pan or bed, frame 10 further comprises frame members 20 and frame members 22, the latter interconnecting upper frame members 18 with frame members 20.

The pan 24 is connected to two pairs of eccentrics 26 and 28 (FIGS. 5 and 6). *Eccentrics 26 are mounted on shaft 30 supported by bearings 32 attached to frame United States Patent 0 members 22, while eccentrics 28 are mounted on shaft 34 supported in bearings 36 and attached to arms 38 freely supported by shaft 40, the latter being supported by bearings 42 carried by frame members 22.

Drive shaft 30 has fixedly but adjusta'bly secured there- Patented Dec. 22, 1970 "ice to a weight 44 positioned in ofiset relation to the eccentrics 2.6, and driven shaft 34 has fixedly and adjustably secured thereto a weight 46 disposed in 180 offset relation to the eccentrics 28.

The drive train for the described system comprises motor 48, belt 50, sheave 52, shaft 54, sprocket 56, chain 58, and sprocket 60 secured to shaft 30. The drive train further comprises sprocket 62 secured to shaft 30, chain 64, sprocket 66 secured to shaft 40, sprocket 68 secured to shaft 40, chain 70, and sprocket 72 secured to shaft 34.

It will be appreciated that the drive eccentric shaft 30, intermediate shaft 40, and driven eccentric shaft 34 are driven at the same rate of speed, that the eccentrics 26 and 28 are disposed generally in the same eccentric phase with respect to each other but need not be finally adjusted to be in identical eccentric phases, and that the two pairs of eccentrics drive the pan with a circular oscillatory movement. The free swingability of arms 38 on the intermediate shaft 40 enables the eccentric pairs to be out of phase with respect to each other without setting up opposing or destructional forces in the system.

Apricots, twigs, etc., which fall through the pocket conveyor, not shown, fall onto the pan 24 and move downwardly thereon to be deposited upon cross-conveyor 74, driven by means, not shown, connected to the drive train above-described, which removes them from the zone of the fruit-handling machine to an appropriate collecting device.

What is claimed is:

1. Apparatus of the type described comprising first and second spaced parallel shafts, support means mounting said shafts for rotation, drive means for rotating said shafts, a pair of eccentrics and a weight mounted on said first shaft in substantially 180 offset relation to each other, a pair of arms pivotally mounted on said second shaft, a third shaft, disposed parallel to said first and second shafts, supported for rotation by said arms, a pair of eccentrics and a weight mounted on said third shaft in substantially 180 offset relation to each other, a panattached to said pairs of eccentrics and adapted to have oscillatory movement therewith, and means driveably interconnecting said second and third shafts.

2. The apparatus of claim 1, said pair of arms depending from said second shaft, said third shaft being disposed at a level below said second shaft, and said first and third shafts being adapted to be rotated at the same rate, with said pairs of eccentrics being positioned to be substantially in phase 'with each other.
